The new giant magnetostrictive material TbDyFe has the trait of output power large
displacement resolving power high and displaclement range great. If the material is used in the micro-displacement actuator
the performance index of displacement actuator will be greatly advanced
which will impel the development of giant precision process technique. In the paper
the structure and the performance of giant magnetostrictive actuator are introduced
and the model of magnet-machine coupling is analysed by the finite element method. It will redound to the computer simulation and the actuator analysis and its design.
